I agree with morris. You don't have enough bracing. It is just going to rip off. Jigsaw it down a little.

Yes I agree with both of you that mine sticks out more then NSS but I don't have the same hull so I figured I would need more surface area. The previous model did not rip apart but it pushed it far enough away from the hull that the mount became loose and slipped off. I didn't want to use rigid ratchets because I would rather the mount slip off then something to break. I will take measurements and trim it down a bit but I would rather have to much so I can trim off then to have to little and have to remake

P.s I'm still testing I didnt expect either one of these to last long enough to actually ride .... I still conduct the test with no ballast just to see if the actual idea will even form a proper wave

Keep us updated on how it goes.

Well ....... Attachment failure..... Clamps no go..... So I have modified it again so I can use a turnbuckle and ratchet strap. However now that it is deff securely mounted I don't think it will work unless you have another ratchet under the platform. When I attach it and pull on it, it looks like its just going to twist the lower section off. Im willing to get in the water to attach the other ratchet but that option is not desirable if it's going to compete with the simplicity of wicked wave/ redneck gate. So I took you guys advice and trimmed it down, but not all the way down to NSS standards but now it only protrudes 2 inches from hull ...... I'm still doubt full that it will hold, I'm going to try it today with and without the under strap to see if it's worth moving forward or not.

Ok so it sorta work but not really and I'm not sure why. I did have to use a strap under the platform which sucks but I was able to test. So the first image is no ballast no wedge at 10.4, it look promising so I moved on

So the next image is no ballast with wedge and still look ok but I starting to see a problem creeping in. the problem is what the arrows are pointing at. But over all still ok so time for ballast. Speed didn't change much 10.4 threw 11.6

Ok so slammed it and it suck, washed out bad and the problem from previous issue was affecting the wave. Speeds 10.4 threw 12. So what do I adjust? Do you think it needs to be flush with transom right now it's close but not perfect. Do you think the Paddle needs to be bigger or smaller? Thoughts ideas welcome.

So there is one positive you did basically have normal steering which my wife like better then surf gate

SO take this with a grain of drinking all day salt....only bother testing with the weight you expect to surf (dry tests is inconclusive). I think the nss needs to come up to the water line when you are fully loaded at idle (in my case its the black/blue seam above the swim deck). I wouldn't worry too much that the hull does not come to right angles against it. I think the engineering key is length of the surface area while minimizing the width. so try something like this:

If you think about a surfgate at a 15' angle, it has the same 2D shadow (void) in the water behind the boat.

So you think it was to far in the water so there was to much coming over the top? And I should make the paddle go higher

Looking at this and some other DIY projects - http://features.boats.com/boat-content/ ... f-on-this/ - it doesn't seem that it is required to be very high. From another thread I think the user went about 2 inches out to the side, but only around 3/4 down from the bottom with his plate.

I think this might work better on boats with a flatter transom. I was thinking about cutting some foam to flatten out the area and then mounting the plat back where I have it shown in this image.

I do think morrisdl has a valid point. even fully sacked out the g's platform is on top of the water, which puts NSS at water line. mine depending on front ballast is usually 5 to 6 inches under water, which would explain why it worked better with no weight. its worth a shot its easy to modify the plate as long as I don't have to modify the mount. I wish I had a better understanding of exactly which part affects what part of the wave

If the surf wave is washed out you need to go faster or bigger nss. If it's clean even at 8mph, it's probably too big and you will lose height at surf speeds. Shape is probably not as important as total surface area. The better you can spead out that ideal surface area , the closer to the hull and less torque on the mount.
